From 6336d4c48d2f85629ff668da36711ea794f70ab5 Mon Sep 17 00:00:00 2001 From: Arthur Heymans Date: Thu, 25 Jan 2018 21:38:25 +0100 Subject: nb/intel/gm45: Use parallel MP init This places the parallel mp ops up in the model_1067x dir and is included from other Intel core2 CPU dirs that can use the same code. Tested on Thinkpad X200 on which boot time is reduced by ~35ms.
